4. ADVANTAGES Low viscosity and easy handling. Stable viscosity at wide P H range. Stable viscosity in long term store. Stable from Microbes & Enzymes. Any rheology of the paint is possible. Cost saving

5. HISOL D Alkali Swellable Associative Thickener

6. Classification of HISOL D

7. CONVENTIONAL THICKENER

8. VOLUME RESTRICTION FLOCCULATION

9. Spatter Paints using conventional thickenersHEC). Volume restriction flocculation : Shear thinning effect : spatter. Paints using associative thickeners : Lower spatter when roll application. Estimate of the roll spatter. Spatter test : Roll 7x2 inch, 1 inch nap, 2ft/sec, 12g of paint, 1x2 ft wallboard. Spatter collection : 9x12 in. Black paper. One feet below the vertical wallboard.

10. Spatter test

11. Spatter test of Interior paint

15. Estimate of the Spatter Roughly : High shear viscosity (shear rate : 10,000/sec). More exactly : Extensional Viscosity

16. Extentional Viscosity

17. Measurement Spinning apparatus (Measure the Extensional Viscosity)

19. RHEOLOGY OF THE WATER BASE PAINTS

20. PAINT FLOW Adjust flow balance Better one coat coverage. Sagging balance. Estimation Low shear viscosity : Graph: Graph Sag-meter, Leveling gauge Zhan cup viscosity.
